5G - BB8, RIGHT alternator CJU75 or CJU76 ?

[paulornothin 22]

Can someone with actual knowledge tell me if there is a compatibility issue with the following 2 alternators.
Having a charging problem I checked all fuses and battery etc and determined I had a bad alternater, mine is a honda oe
Info on its label is :-
REGULATOR BUILT IN OR
Honda CJU75
101211-9750
I ordered one from a breakers that quoted the same info as mine, when it came , it looked identical but the label differed as follows
OS not OR
CJU76 not CJU75
9760 not 9750
I've fitted it and initial impessions are ok driving steady, I realise it just could be a superceded part number but
It was supposed to have come off a 97 reg same as mine

Thanks in advance to someone who knows their auto-electrics
